3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Spontaneously flammable in air. Harmful if swallowed. Irritating
to eyes, respiratory system and skin.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.

10 - Stability and Reactivity
STABILITY
Stable: Unstable.
Conditions of Instability: May decompose on exposure to moist air
or water.
Conditions to Avoid: Strong reducing agent. Violent exothermic
decomposition occurs above 100'C with emission of large amounts of
sulfur oxides, ammonia, carbon monoxide, carbon dioxide, nitrogen
oxides and hydrogen sulfide. Prolonged exposure to moisture and
temperatures above 50'C may also cause violent exothermic
decomposition.
Materials to Avoid: Strong oxidizing agents, Strong bases.
HAZARDOUS DECOMPOSITION PRODUCTS
Hazardous Decomposition Products: Carbon monoxide, Carbon dioxide,
Nitrogen oxides, Sulfur oxides, Ammonia.
HAZARDOUS POLYMERIZATION
Hazardous Polymerization: Will not occur
